1 Claim. 1

This invention relates to a wheel chock and has for its principal object the provision of a wheel chock which can be used for securely blocking the wheels of any type of wheeled vehicle and which, when not in use, can be folded fiat for convenient storage in the vehicle.

Another object of the invention is to so construct the device that it will be light in weight, easy to fold and unfold and highly eiiicient in use.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawings:

Fig. l is a perspective View of the preferred form of the improved wheel chock illustrating it in the folded position;

Fig. 2 is a similar view illustrating the improved wheel chock in the open position ready for use;

Fig. 3 is a perspective View of an alternate form of the improved wheel folding chock in the open position; and

Fig. 4 is a longitudinal section through the chock of Fig. 3 illustrating it in the folded position.

The form of chock illustrated in Figs. 1 and 2 is designed for use on passenger automobiles, aircraft and the like. The type illustrated in Figs. 3 and 4 is more particularly designed for heavy vehicles such as trucks, buses and coaches. The improved wheel chock consists of three U-shaped members, a frame member ID, chock member I I and a brace member I 9, a chock member II and a brace member I2. All three of the members are formed by bending bars into a substantially U-shape having two side portions connected by a cross portion. The sides of the brace member I0 and the sides of the chock member are hingedly secured together at their extremities upon hinge rivets I3 so that the chock member may be swung inside the frame member II], as shown in Fig. 1. The extremities of the sides of the brace member I2 is hingedly secured to the sides of the chock member II adjacent the cross portion of the latter by means of hinge rivets I4 so that the cross portion of the brace member will fold inside the rivets I3 as shown in Fig. 1. The cross portion of the chock member II is inwardly curved as shown at I5 to receive the tread of an automotive tire casing.

When desired for use, the chock member I5 is swung upwardly from the brace member ID and the brace member I2 is swung downwardly and forwardly within the embrace of the frame member II! as shown in Fig. 2.

The cross portion of the frame member Ill is then forced beneath the wheel of the vehicle allowing the tire tread to rest in the indented portion I5 of the check member II, as shown in Fig. 2.

In Figs. 3 and 4 an alternate form of the device is illustrated employing a U-shaped base frame member It similar to the frame member is of the previous form. In this form, however, a U -shaped chock member I! is employed formed of angle iron which is hinged upon hinge rivets It at its open side to the extremities of the frame member It. The angle iron I7 folds down around the base frame It as shown in Fig. 4.

In the working position the angle iron member I! is supported in the position of Fig. 3 by means of an angle iron brace frame I9 which is bent in a U-shape to fit within the frame I I. The brace frame is mounted on pivot rivets 29 adjacent the cross member of the base frame I6. When in uses the device has the appearance of Fig. 3 and when folded the appearance of Fig. 4.

While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied, within the scape of the appended claim, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

A wheel chock comprising: a U-shaped frame member; a U-shaped chock member, said chock member being smaller than, and telescoping within, said frame member, the two extremities of the chock member lying within and against the two extremities of the frame member; a pair of hinge pins securing said extremities together; a U-shaped brace member telescopically fitted within said U-shaped chock member, said brace member being faced oppositely from the first two members so that its extremities will project oppositely to the extremities of the former members; and a second pair of hinge pins securing the extremities of said. U-shaped brace member within said chock member adjacent the midportion of the latter.
